Just got it running but had to use Uboot method. Using the normal UI would not work. Some problems I’ve noticed so far. Picture of errors I get when trying to go to advanced menu. Also, no led indication for LTE connection although I’m online and using right now. The major problem is not being able to access the advanced menu and see what it is showing for firmware version. I assume it is 19.xxx. Thanks and hope this helps. I may revert back if connection gets unstable but will try to stay on this in case you have more questions or want me to try something. Thanks.
